Prestressed pipe pile splicing method
The invention discloses a prestressed pipe pile splicing method. The prestressed pipe pile splicing method comprises the following step that S1, soil around prestressed pipe piles is excavated with the prestressed pipe piles as the centers, the prestressed pipe piles are poured and fixed and stand for a period of time, and the length of the prestressed pipe piles needing to be spliced is measured. According to the prestressed pipe pile splicing method, pile heads of the pile cutting parts on site are reused, the ends, provided with steel sleeve plates, of the pile heads are buckled and welded to the tops of the prestressed pipe piles, and the bearing capacity of the prestressed pipe piles is guaranteed through combination of the prestressed pipe piles of the same batch at the same time; and the pile splicing method is simple in procedure, the prestressed pipe piles spliced are almost the same as original pipe pile concrete in strength grade, the problems that in the prior art, after construction of the prestressed pipe piles is completed, the pile top elevation of part of the pipe piles cannot reach the preset height, pile splicing treatment needs to be conducted, according to the method concentrated in the current figure, the pile splicing method is complex in procedure, and the prestressed pipe piles spliced are almost the same as the original pipe pile concrete in strength grade are solved, and the accuracy of a device is improved.
本发明公开了一种预应力管桩接桩方法，包括以下步骤：S1、首先以预应力管桩为中心开挖预应力管桩四周的土壤，对预应力管桩进行浇灌固定，静置一段时间，测量需要接桩的长度。本发明通过将现场截桩部分桩头再次利用，通过将桩头带有钢套板的一端与预应力管桩的顶部进行卡扣之后焊接，通过同时同批次预应力管桩组合，保证了预应力管桩的承载力，接桩方法工序简单，与且接桩之后的预应力管桩与原有的管桩混凝土强度等级相差无几，避免了现有技术中，预应力管桩施工完成后，部分管桩桩顶标高达不到预定高度，需进行接桩处理，按照目前图集中的做法，接桩方法工序较复杂，与原有管桩混凝土强度等级相差甚多的问题，提高了装置的精确性。
